# With special lengths supplied by user space, register_shm_helper() has # an integer overflow when calculating the number of pages covered by a # supplied user space memory region. # # This causes internal_get_user_pages_fast() a helper function of # pin_user_pages_fast() to do a NULL pointer dereference: # # Unable to handle kernel NULL pointer dereference at virtual address 0000000000000010 # Modules linked in: # CPU: 1 PID: 173 Comm: optee_example_a Not tainted 5.19.0 #11 #
